Many on the sash balance did not have any markings. I included a sticker that was on the window related to inspection.

It's hard to say. Check the width of the bottom side aligners. If they are 15/16", I recommend our 18-185 top sash guide.

The window has a channel which is 13/16 at the narrow point. The fins on the guide are 31/32" wide and fit in the wider part of the channel. Probably a 3/4" wide guide with the correct size top would work but I could not find one on your site.

Ah, I see! With this new information in mind, I think our 18-138 top sash guide might work for you sash. It has those same aligners at the bottom of the guide for the balance channel. See what you think.
